"Mastering Monero: The future of private transactions" is your guide through the world of Monero, a leading cryptocurrency with a focus on private and censorship-resistant transactions. This book contains everything you need to know to start using Monero in your business or day-to-day life, even if you've never understood or interacted with cryptocurrencies before. The first portion of the book is a friendly (non-technical) introductions to key concepts and skills - chapters 1 and 2 start from scratch, and cover everything you need to know to transact safely. For curious readers, chapters 3 and 4 conceptually explain how Monero's blockchain and privacy technologies work (no math). Later chapters dive deeply into the internals of Monero, its mathematics, its code, and how to contribute. Current digital cash systems such as Venmo and Bitcoin bring convenience at the expense of staggering privacy concessions. Corporate solutions such Venmo are often "free" because selling transaction data is more profitable than charging fees. Users increasingly need to share sensitive information with others just to send money to friends, family, and merchants. It is a common misconception that any cryptocurrency (e.g. Bitcoin, Ethereum, etc) is anonymous and private; however, they are effectively transparent. Their public ledgers allows anybody in the world to see account balances and payments. Entire industries exist around tracing cryptocurrency activity, and linking it to real-life identities. Monero protects your sensitive personal financial information to prevent this type of surveillance and allow you to transact safely with peace of mind. You are the owner of your own private bank. You can interact in the digital world without forfeiting your rights.
